Question : Directions: Select the option in which the numbers are related in the same way as the numbers in the given set.
(11, 23, 47)
Option 1: (17, 35, 69)
Option 2: (13, 27, 54)
Option 3: (19, 39, 79)
Option 4: (23, 46, 93)
Correct Answer: (19, 39, 79)
Solution :
Given:
(11, 23, 47)
(11, 23, 47)→(11 × 2) + 1 = 22 + 1 = 23; (23 × 2) + 1 = 46 + 1 = 47
Let's check each option –
First option:
(17, 35, 69)→(17 × 2) + 1 = 34 + 1 = 35; (35 × 2) + 1 = 70 + 1 = 71
≠ 69
Second option:
(13, 27, 54)→(13 × 2) + 1 = 26 + 1 = 27; (27 × 2) + 1 = 54 + 1 = 55
≠ 54
Third option:
(19, 39, 79)→(19 × 2) + 1 = 38 + 1 = 39; (39 × 2) + 1 = 78 + 1 = 79
Fourth option:
(23, 46, 93)→(23 × 2) + 1 = 46 + 1 = 47
≠
46; (46 × 2) + 1 = 92 + 1 = 93
So, (19, 39, 79) follows the same pattern. Hence, the third option is correct.
